2.4. Explanation of symbols
Pictograms located on the compressor are described below. Explanation is provided
below any of them.
For technical reasons, it is impossible to attach pictograms in the very vicinity of the
points of risk.

3. Setting
3.1. Room requirement
-
The compressor requires no foundations. It must be seated on a hard and even
surface. Consider load capacity of the floor-ceiling, if the machine is installed in a
building.
-
Strictly observe the minimum distances from walls and other machines. In case of
installation of several compressors, pay attention to the direction of cooling air flow;
no compressor should suck air which is heated by other machine.
-
Protect the room in which the compressor is installed from negative temperatures.
The inlets and outlets to and from the room should be located in such a manner to
protect the interior from weather conditions.
-
Heat generated during compression should be extracted outside (or to other
rooms), and fresh air should be supplied from the outside.
-
If the gravity ventilation is insufficient (windows, openings in wall etc.) in the
compressor room, force air exchange using ventilators. To ensure sufficient heat
extraction, the ventilators should have summarised capacity around 15 – 20 %
higher than the total cooling air requirement for all compressors in the room.
-
The air temperature in the room should range b5°C to +40°C.
-
Provide sufficient room for maintenance operations.
3.2. Power supply system requirement
The booster compressor is designed to be supplied by a five-conductor 400 V AC, 50 Hz
power line. If only four conductor line is available, bridge the PE and N terminals in the
cabinet terminal block.
The cross sectional area of conductors should be matched to the current drawn by the
booster compressor.
-
3 x 50 mm
2
+ PE wire is recommended for the KOMPBERG BKB22 TWIN with a
motor power output of 45 kW (i.e. 2x22 kW).
The KOMPBERG BKB22 TWIN booster should be supplied from a switchgear
provided with a time delay fuse (rated for 125 A) and a breaker allowing to completely
cut the power supply out.
Connect the compressor as specified in the attached electric diagram.
3.3. Compressed air connection
Connect the compressor to the compressed air system with a flexible conduit.
It is recommended to use galvanized steel or plastic tubing for the compressed air
system. If conditioning equipment is provided for the compressed air (filters, drier), the
existing piping should be replaced with a new one, unless the air supplied previously has
not been conditioned by similar equipment.
